Connect ChatGPT to VCAD
Let ChatGPT read the session you have open in VCAD and suggest changes for you to accept, or do the work automatically.
Once you are done, VCAD is under Installed on the Plugins page in ChatGPT with your VCAD account connected, and the AI box in VCAD says Connected. You set it up once on chatgpt.com in your browser.

Click the Modules tab.
Click the switch next to AI-Bridge.
Click the copy button inside the field with the address
https://mcp.vcad.dk/mcp. The button briefly turns into a tick, and the address is copied.Under AI Mode, choose whether ChatGPT asks first: with Ask every change waits for you to accept it, and with Auto it is in the drawing at once.

Give ChatGPT access to VCAD

Use ChatGPT with VCAD
Keep the session open in VCAD. The AI box in the bottom right corner says Connected.
In a new chat, ask ChatGPT for something in plain words, for example "Find every point with the code WELL, put a well on each of them and draw the pipe between them with its slope" or "Set all points on layer Terrain to elevation 2.5". With AI Mode on Auto, the change is in the drawing at once. With Ask, it appears in VCAD as an AI change proposal.
If AI Mode is on Ask, click Zoom to change.
Click Accept. The change is in the drawing.
If something doesn't work
| What you see | What to do |
|---|---|
| ChatGPT cannot get hold of your session | Open a session in VCAD. Check that AI-Bridge is on and that the AI box says Connected. |
| VCAD's Settings has no Modules tab or no AI bridge | AI comes with a VCAD Pro license. Ask your VCAD administrator to give you one. If you are the administrator, choose Administration when you sign in, and tick the box next to the user under Users in the column for Pro. |
| AI module not enabled | You do not have a VCAD Pro license. Do as in the row above. |
| Reconnecting… | VCAD has lost its connection and keeps trying again. Check your internet, and reload the page if it stays. |
